Corn is a warm-season annual that is best planted after the soil temperature reaches 60Â°F, usually two or three weeks after the last frost in spring. Corn planted in cold, wet soil is unlikely to germinate. Corn grows best in air temperatures from 60Â° to 95Â°F.Corn can take from 60 to 100 days to reach harvest depending upon variety and the amount of heat during the growing season.orn seed germinates in 10 to 14 days at 75Â°F, but the rate of germination may reach only 75 percent. Start corn indoors 2 to 3 weeks before the last frost in spring for transplanting 2 to 3 weeks after the last frost. If your season is long enough, plant successive crops every two to three weeks. Planting and spacing.
Sweet Corn. Grown for eating fresh on the cob or freezing and canning, the height of sweet corn stalks varies greatly. Some early season varieties of sweet corn such as Early Sunglow, only reach 4 to 5 feet in height. Later season varieties such as Jubilee typically grow 7 or more feet tall.New sweet corn varieties designed to grow in pots or containers may only reach 4 or 5 feet tall.orn plants consist of a single stem or stalk with leaves and ears attached. The height of the stalks depends on the corn variety and the environment. On average, a corn plant measures 8 feet tall but the world record is over 30 feet.
